just make an ipconfig /all so we can see whats your network card configuration...
For access to any 192.168.0.x you need to be on the same network, that means your card is on 192.168.0.something too, check your netmask is correct (if class C 255.255.255.0) and the same on the miner.
If everything is correct, just check if the arp address is correct and updated.
ping 192.168.0.101
arp -a
(you need to check if the mac and the address is correct, if not)
arp -d *
If this doesn't work, you can restart your computer.
If this doesn't work neither consider using a sniffer to watch what is happening.
P.S. I assume you use windows or you wouldn't asking this question.
